Dear Bertrand,

I confirmed with PG14 that tuple concurrently updated ERROR can be raised when
ALTER SUBSCRIPTION DISABLE happens concurrently:
```
postgres=# ALTER SUBSCRIPTION sub DISABLE ;
ERROR: tuple concurrently updated
```
It might be harmless but I think the correct ERROR should be reported: the patch
should be backpatched. Thought?
